No, that error is not the "good" error, which should only be
happening around 0 to 100 nsm (for a clock running @ 10 MHz).

The error you have posted is a result of the PC's 3rd bit
(eg, the one in the 2^2 position) becoming undefined (I can't
say why at this time). Essentially the simulation is saying that
there is no address in the EPROM at 00000U00.

Look closely at what is happening before your PC outputs this bad
value.
